STUCCO BASE Filed May 1e, 192e "E TTK Patented Jan. 7, 1930 UNITED STATES PATENT OFFICE JAMES W, WRIGHT, OF LOS ANGELES, GALFORNIA STUCCO BASE Appncation fued May'is, 192s. serial No. 278,140.

My invention relates generally to build-` ing material, and more particularly to a stucco base and the principal object of my invention is to provide a base or anchoring 5 member that performs thefunctions of a I in construction, inexpensive of manufacture,-

and which may be easily and quickly applied to building walls or other structures that are to be covered with stucco or the like.

A further object of my invention is to provide a stucco base member that is constructed so that it may be laid in c ourses after the manner of rough shingles with the exposed 25 portions of the base members being overlaidv with reticulated furring material, such asv expanded metal, wire netting or the like, with portions of said furring material interposed between layers of felt or the like, which form the bodies of the base members, and these interposed portions of the furring material being located so as to receive the nails that fasten the base members'to the building wall or other structure. j

Further objects of my inventions are to provide a stucco base which, when properly. j laid, provides an air and moisture-proof covering, and which base will permit the coating of stucco or the like to expand and contract to a considerable degree, Without cracking. Y

WithV the foregoing and other objects in view, my invention consistsV in certain novel features of construction and arrangement of scribed and claimed and illustrated in the accompanying drawing, in .which- Fig. 1 is an elevational view of a stucco base member constructed in accordance with my invention.

' able parts that will hereinafter be more fully de` Fig. 2 is a cross section taken on the line 2-2 of Fig. l.

Fig. 3 is a cross section taken on the line 3-,3 of- Fig. 1.

YF'g. 4 is a cross section taken on the line 4 4 of Fig. l. f

Fig. 5 is an elevational viewof a number of the stucco base members assembled'or laid in courses to form a continuous furred surface for the reception of stucco, plaster or the like. l

Fig. 6 is an enlarged vertical section taken on the line 6-6 of Fig. 5.' V

Referring by numerals to the accompanying draw-ings, l0 designates the yinner or rear layer of the body of thel base,'.the same being preferably formed of lfeltfpaper or the like, andthe `length of ywhich ris substantially greater than the width, and overlying the upper front portion ofthe back layer, is ,a front layer 1l of the felt paper, or the like, that is secured to the back layer by a suitadhesive, preferably asphalt. yThe width of the front layer ll, is equal tothe .width of the rear layer, but the length of said front layer is somewhatless than said rear layer, so that the lower edge of the .front layer terminates several inches above the lower edge of the rear layer.

.Overlying that portion` of the rear layer 10, below the lower edge of the front layer 11, is a substantially rectangular section 12 of self-furring material, preferably expanded sheet metal, woven wire or the like, and the upper edge of this furring metal 'extends upwardly a short distance between the layers 10 and 11 of felt, and this interposed portion ofthe metal is secured to the layers v1() and 11 in Vany suitable manner, preferably by means of asphalt. v

If desired, the furringmetal may be bent outward a short distance just below the lower edge of the front layer y11, thus-forming a transversely disposed shoulder against which the'lower edge of an overlying base member is arranged when the members are laid in courses on av building wall or the like.

In laying the base members constructed as just described, a number of said members are arranged side-by-side to` form a course,

and by means of nails driven thru said members just above the lower edges of thefront layers 11, said members are firmly secured to the sheathing or building structure. Inasmuch as the upper portions of the furring metal extend beneath the lower edges of the front or outer layers l1, the interposed sections of wire serve as firm anchorage for the nails that are utilized in securing the base members to the building structure, and when the succeeding course of base members are applied to the first laid course, the lower portions of the second course of said meinbers overlie the heads of the nails utilized in fastening the members of the first Course,

and this arrangement is continued until the" area to be covered with the members is entirely overlaid. i

In laying the base members, the joints between the succeeding courses are broken after the manner of broken joints between shingles, tile and the like,

V- ternperatures will cause, stucco and the like When the basemembers have been properly applied to the surface that is to be covered, the sections 'of furring metal 12 present a practically continuous furred surface that receives the stucco, plaster or other hardening material, and portions of the latter, when applied, pass thru and key behind the metal and thus, the Vfinishing coat of self-hardening plastic material is very securely anchored to thebase members, and an air and moisture-prooi1 covering surface is provided.

Eventho the stucco or plaster should become broke, the overlaid double layers of feltpapers that form the bodies of the base members covering tor the underlying building structure, thus insuring a warm, dry and cornfortable interior.

It is a well established fact that'varying to expand and contract, and if no provision is made to permit such expansion and 4contraction, the structure, plaster or cement will crack and break. In my improved base, provision is made to permit expansion and contraction of the stucco, cement or plaster outer coating, for the nails that are utilized in securing the base members to the building structure pass thru those portions of the furringmetal that are spaced apart from the portions that receive the stucco or plaster coating, and thus, the layers of felt and thel interposed furring materialy immediately surrounding the nails providea cushion base that will yield readily under varying degrees of temperature, thus permit the coating of stucco, cement or the like, to move for a limited distance, as a result of expansion or contraction, and which action takes place without cracking or checking.

Practically all stucco or cement walls will sweat as a result of varying temperature conrovide an air and moisture-proof ditions, for instance, relatively cool nights and warm or hot days, and such conditions produce, by condensation, moisture on the inner surface of the body of stucco of cement, and unless the cement or stucco is laid on an absolutely moisture-proof base, this condensation will pass thru to the inside plaster, thereby causing dampness on the surface of said plaster and consequent injury to the interior decorations.

In my improved base, the double layers of the overlaid felt sheets that form the bodies of the base, effectually prevents moisture passing from the stucco body inwardly, to the interior plaster and at the same time, eifectually prevents the inward passage of air and consequently, provides awarm interior.

Thus, it will bie seen that I have provided a stucco base that is relatively simple in construction, inexpensive of manufacture, capable of being easily and quickly applied for use and veryef fect1ve in performing its intended functions.

It will be understood thatminor changes in the size, form and construction of the various parts of my improved stucco base may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims,
